Title:
  alpha blur muddy when animated

Status in OpenShot Video Editor:
  New

Bug description:
  1) Ubuntu 12.04
  2) Openshot 1.4.0
  3) none

  The attached video shows the issue, the same alpha image is displayed, the first four seconds without any set animation (except for the correctly working fade in). Note the white, shiny blurred text copy (its a png file exported from inkscape, see further attachments).
  From second 5 you can directly see how starting the animation (Zoom in 100 to 50) now turns the blurred part grey, muddy. Apart from being less beautiful than the first version, the two should not differ in optics whether applying an animation or not. After a short test it looks like all fades work correctly (with the white being shiny and nice) and all the animations on the clip are affected from turning the blurred alpha part muddy, grey.

  Would be great if this could be fixed, since it makes transitions
  between fixed and animated state very ugly, but also animation in
  itself looks much less nice (at least with white blur) than the
  unanimated version.

  Thanks for this wonderful tool none the less! :)
